The Lowdown
Alright, I’m gonna be straight with you. This is a tough stretch for Kennebunk Beach. The whole 16-day window is a real struggle. We’ve got a solid two weeks of nothing but small, weak, and mostly messy conditions. The energy just isn't there. The combined swell energy is barely cracking 20 or 30 in the early days, just tiny little windswells with no push. You’ll be looking at knee-high slop at best, with a lot of cross-onshore winds chopping it up. It’s one of those times where the forecast looks bleak, and it’s going to stay that way for a while.
The one and only time this picture changes is right at the very end. On Thursday, August 20th, we get a real spike of energy. The morning shows a 7ft swell from the east, with a combined energy of 427 – that’s a serious pulse of power. But here’s the thing: that’s a lot of water moving, and it’s coming with a short period of 7 seconds and a strong onshore wind. It’s going to be a raw, heaving, and probably pretty ugly mess. For a sheltered beach break that’s already inconsistent, this is less of a surfer’s dream and more of a kite surfer’s playground. The afternoon cleans up a little with a cross-offshore wind, but the swell is still 6ft and the period is still short. It’s a raw, powerful, and chaotic day that really only experts should even think about. The following morning, Friday, August 21st, is the most promising with a 4ft easterly swell and a clean, cross-offshore wind from the north-northwest. That’s your best shot, but it’s still a one-off window in a long, flat run.
To be honest, the water temperature is about average for the time of year, so you won’t get a shock from a cold snap, but it doesn’t help the waves. Kennebunk Beach is a fairly consistent spot normally, but this 16-day window just doesn’t have the goods. I’d say keep the board in the car for that Friday morning the 21st and maybe the 22nd, but don’t hold your breath.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
